Happy new year!

On Linux, calling periph.WriteCharacteristic(characteristic, []byte{...}, true) after the connection to periph has been closed blocks indefinitely. This makes it impossible to guarantee we can let the goroutine calling WriteCharacteristic know when to stop calling it. Returning an error on write seems like better behavior.
